Abstract
A method for inhibiting corrosion of metal surfaces, such as carbon steel tubing, that are in contact with a fluid, such as brine in an oil and gas production fluid containing acid gases (e.g., COand HS) is accomplished by introducing a corrosion-inhibiting blend of two components into the fluid, where blend is glycolipids and quaternized amines, glycolipids and phosphate-containing compounds, quaternized amines and imidazoline-like compounds, quaternized amines and phosphate-containing compounds, or combinations of these blends. Each of the two components of the blends are present in an amount effective to synergistically inhibiting the corrosion of the metal surface when used together.
